The correct answer is Coimbatore.
Coimbatore, in Tamil Nadu, has been called the Manchester of South India because of its long history as a textile hub. The city has a large number of cotton spinning and weaving mills, much like Manchester in England, which was the centre of the world cotton industry during the industrial revolution.
Coimbatore is also known for engineering goods, pumps, and motors, but it earned this nickname mainly through its textile industry.
